DACs use a proprietary soft-connect algorithm to minimize supply disturbances. Supervisory functions include over and under voltage and temperature threshold limits for two power supply output channels and one input channel. Programmable fault responses can disable the power supplies, configure retry, and trigger black box EEPROM storage of fault status and associated telemetry.
